I own a condor .25 cal SS.
I have the slap mod and the high air flow top hat that I got from this guy:
http://talontunes.com/shop/condor-hammer-with-slap-modification/ http://talontunes.com/shop/quick-change-top-hat/ Overall I really like it. I will comment and post a few things on it as time goes by. There have been some interesting points made by folks so far in this thread. Let me see if I can address them.
1. how accurate is it (e.g. grouping performance between shots from the same condor)?
2. how consistent is Airforce as manufacturer at consistently producing this standard deviation in their equipment (e.g. grouping performance between one condor vs a population of other condors)?
3. how comfortable is it to shoot?
4. how easy is it to work on?
Question1: I can say that I can constantly knock down 12ga empty shot shells at 75 yards with a 4-5mph cross wind all day long. I have yet to do an actual grouping with this rifle. I set out to, but when I found myself hitting everything I was shooting at, then I lost interest. same hole at 50 yards is typical when im siting this thing in. It does shoot better and a lot harder with the aforementioned mods above. I can see about 90ft-lbs using a 70gr "black-mamba" round. I have to tone it down to about 50 ft-lbs for the Benjamin pellets 28gr? im using. Don't bother with the power wheel that comes with it. tune up power wheel near about 8, set it, and leave it alone. constantly dialing the power wheel around creates unacceptable variation in my mind and isn't worth fooling with. get the heaver hammer and top hat and use the flow nozzles to adjust power (see link above).
Question2: I will not attempt to address question 2. as I only own one unit and a study of this kind isn't valid until you have a sample size far more significant and uniform than anything the I can provide.
Question3: this is the most uncomfortable air gun I have ever held in my hands. In contrast, my favorite so far is the fx boss (lefty model). the tank is too sort as a rifle stock and I feel like im shooting a kid's gun. the hand grip is very un-ergonomic, and the trigger is hokey. But we are talking comfort not trigger control. The trigger has a very manageable release point and weight to it for very accurate and consistent shooting so it is uncomfortable as hell, but does perform just fine. I will note the mounting rail along the top and bottom are nice, but seemingly proprietary and converting to pickatinny costs again more money.
Question4: I have taken this thing apart, and read about all the mods one can do to this thing including shooting .257 bullets from it at 100+ ft-lbs. I have yet to experiment with this but I intend to. if I can make this into a 200+ yard gun I will. very simple design, swapping barrels, and other parts is pretty simple. If one owns a machine shop, this thing would be a dream to mod up and change around (aftermarket parts seem pretty prevalent too).
I have a slo-mo camera hooked up to it and I have been hitting a 2" metal fence post at 133yds in my back yard pretty consistently. As soon as I can figure out how to post and edit these I would be happy to share. I will give a few photos as well if anyone is interested. I have some jsb pellets on order I want to see how different they perform.
OVERALL: this air gun is a very strong performer (exceeded my expectations for the price point). very versatile (low price point but tones of things you can change about it, including barrels, calibers, power settings etc.) that being said, there is so much to add to this thing you can make it a 1500$ gun pretty fast. If you want something that you can change around for different purposes and like to tinker, I would say get one you wont be disappointed. If you are looking for a out of the box hunting appliance that you just pick up and use, I would not recommend it at all.
hope this helps...
